Hi @netsolom,
Two things I could find/spot:
- the status is not shown in the 
inventorytab, but theidentityone. - there have been bugs in older versions concerning the sync of 
inventoryanddeviceauth. You can check Mender 2.5.0 Problems with Filters, Hostnames and More - #2 by mzedel if it helps. 
Greetz,
